<br />Sketch Plan: Kings Island Townhomes <br />July 28,2006 <br />20f4 <br /> <br />Density: Net density is calculated exclusive of wetlands within the plat boundaries. The sketch <br />plan submittal' indicates that the total site area is 5.22 acres, and that the new lot created to <br />contain the existing building on Highway 10 is 1.02 acres, which leaves 4.2 acres for the new <br />single-family lot and detached townhomes. This results in a gross density of2.9 units/acre for the <br />residential portion of the plat. The R-2 Residential District has a minimum net density of 3 units <br />per acre and a maximum of 7 units per acre. Net density will be verified at the time of <br />preliminary plat. <br /> <br />Setbacks: If processed under the new R-2 detached townhome regulations, the following <br />setbacks will apply to the detached units: 25 feet from public and private streets, 25 feet from <br />exterior development boundary line, and a 10- foot building separation (depending on final <br />direction from the City Council on the new standards). The single-family lot must accommodate <br />a 35-foot front. yard setback, 10-foot side yard setback, and a river setback of 20 feet from the <br />bluff line or 100 feet from the Ordinary High Water mark, whichever is greater. Any wetlands on <br />the property will require additional setbacks per the Wetland Buffer ordinance. Setbacks must be <br />shown on the site plan submittal, to accompany the preliminary plat. <br /> <br />Lot Standards: There is no minimum lot size or width for .the detached townhome units. The <br />single-family must be at least 20,000 square feet in size with a 90-foot minimum lot width. The <br />"single-family lot is limited to 30% impervious surface. The portion of the plat to contain the <br />"detached townhomes is limited to 35% building coverage. <br /> <br />Open Space: The R-2 District requires 40% of the site to be preserved as open space, including <br />grassed lawns, landscape areas, gardens, naturaC areas, wetlands, and ponding areas. 10% of this <br />area must be dedicated as an identifiable common area for use of the residents. Open space <br />calculations are required as part of the site plan/preliminary plat submittal. <br /> <br />Landscaping and Tree Preservation Plan: The City's Tree Preservation ordinance applies to <br />this plat. A tree preservation plan will need to be included as part of the preliminary plat <br />submittal. The plan should include all existing trees on the property that are four (4) inches or <br />greater in diameter indicating the species, size, location, and any pertinent comments regarding <br />tree condition. Furthermore, a landscaping plan will also be required according to the R-2 <br />landscaping requirements in City Code. Existing trees that are preserved throughout the <br />construction process may be credited toward planting requirements based on size, species, and <br />location. <br /> <br />Density Transition: City Ordinances require a transition between higher density developments <br />and lower density developments. This ordinance will require some type of transitioning between <br />the detached townhomes and the existing single-family lots on Rivyn Avenue. Acceptable forms <br />of transitioning include a landscape buffer, a reduction of density along the perimeter of the' <br />development, or any other transitioning technique mutually agreeable between the ,City COlJIlcil' <br />and the Developer. Staff will also be recommending some type of buffering between the detached <br />townhomes and the existing businesses on Highway 10. <br /> <br />70 <br />
